Just a short explanation about the referral system to all the confused (at least, according to how it worked on previous bundles):
Every MH users (regardless of if they had bought the bundle yet or not) got a referral URL that led too the bundle purchase page. When someone else (anyone, MH user or not) bought the bundle using this referral URL, the user who's URL was used got a "referral point". These points unlocked additional apps from the bundle, and there has always been several pretty sweet apps at the 1 point tier. So, a very popular strategy is to "trade referral URLs", meaning 2 MH participants buy the bundle using each-other's URLs which results in the apps getting unlocked for both of them. You can then continue spreading your URL to other non-MH-participants all you like, trying to unlock the rest of the apps (that I've never found myself really wanting anyway... but that depends on the bundle).
So, to some it all up, my suggestion is that instead of everyone rushing off and buying the bundle the second it is revealed, in the case that a referral system exists this time around as well, we should all pair up within our team (because our team rocks) and make sure that as many as possible have at least the 1 referral app unlocked for them.
